Heirloom Celery Seeds
Heirloom / Open Pollinated Celery is one of the most challenging vegetables to grow, requiring a frost free (weather fluctuations and 7+ cold nights will cause young plants to “bolt” or set seed prematurely), cooler climate, with a long season, and plenty of water and nutrients. Start Celery seeds indoors 8-10 weeks before last frost . Plant seeds 1/8″ deep. Germination should occur in 10-20 days at 55-70°F. Transplant Heirloom / Open Pollinated Celery when outdoor soil reaches 55°F. Set out in full sun, spacing plants 10-12″ apart, in rows 18-24′ apart. Harvest Celery when stalks large enough to use and have developed good color. Can harvest Celery stalks individually or pull whole plant and cut off roots.
